Your entire comment is basically an asinine way of talking around the fact that employers want people to go to work in places that they can't actually afford to live or must otherwise waste vast portions of their lives and pocketbooks commuting to work. Perhaps I'd be more sympathetic if employers were taxed on their employees' commute distance and time, or had to pay overtime rates for employees commutes, even for salaried workers, or something, but as it stands people don't "feel like they must live in Manhattan." Instead, they feel like they have to work for whatever company that's got good vibes, aligns with their career (because network effects are very real), and locates their office or coworking space in SF or Manhattan, and then don't want to spend all their salary on rent or commute 2 hours each way.
